Monitor your firewall activity by tracking and reviewing the log data.
After configuring the iptables prefixes, you'll need to open up firewalltailler in a text editor and configure the color coding and text replacement for the output. Examples are provided to make this process easier. You'll also need to toggle $doDNS to 1 or 0 depending on whether you want DNS lookups for local IPs. Once everything is configured, simply exit the text editor and run the program.
Overall, because of the setup involved, Firewalltailer may not be the best choice for casual users or those who don't have the time or patience to configure it properly. However, for more advanced users who are willing to put in the effort, it can be a powerful tool for monitoring firewall traffic and identifying potential issues.
